Pete is one of the six araxyte pets that may be obtained by killing Araxxor and Araxxi. Araxyte pets are very rare drops from Araxxi, although the chances to obtain one may be increased by a player sacrificing their drops in a given kill. After one of them is obtained in a drop, the rest must be unlocked by completing various tasks within the Araxxor fight, after which it will automatically be added to the pet interface. Pete may be unlocked by simply killing Araxxi during a fight where Araxxor is in his magic form.

Like the other pets, Pete shares his designs with one of the lesser araxytes that features in the boss fight, in his case an imbued spider.
